Combined effects of inversion and feature removal on N170 responses elicited by faces and car fronts
(Elsevier, 2013-02-28)The face-sensitive N170 is typically enhanced for inverted compared to upright faces. Itier, Alain, Sedore, and McIntosh (2007) recently suggested that this N170 inversion effect is mainly driven by the eye region which ... -
Early sensitivity for eyes within faces: A new neuronal account of holistic and featural processing
(Elsevier, 2014-08-01)Eyes are central to face processing however their role in early face encoding as reflected by the N170 ERP component is unclear. Using eye tracking to enforce fixation on specific facial features, we found that the N170 ... -
Effects of task demands on the early neural processing of fearful and happy facial expressions
(Elsevier, 2017-05-15)Task demands shape how we process environmental stimuli but their impact on the early neural processing of facial expressions remains unclear. In a within-subject design, ERPs were recorded to the same fearful, happy and ... -
Fixation to features and neural processing of facial expressions in a gender discrimination task
(Elsevier, 2015-10-01)Early face encoding, as reflected by the N170 ERP component, is sensitive to fixation to the eyes. Whether this sensitivity varies with facial expressions of emotion and can also be seen on other ERP components such as P1 ... -
From eye to face: The impact of face outline, feature number, and feature saliency on the early neural response to faces
(Elsevier, 2019-11-01)The LIFTED model of early face perception postulates that the face-sensitive N170 event-related potential may reflect underlying neural inhibition mechanisms which serve to regulate holistic and featural processing. It ... -
Increased Early Sensitivity to Eyes in Mouthless Faces: In Support of the LIFTED Model of Early Face Processing
(Springer, 2018-07-09)The N170 ERP component is a central neural marker of early face perception usually thought to reflect holistic processing. However, it is also highly sensitive to eyes presented in isolation and to fixation on the eyes ... -
Is it about me? Time-course of self-relevance and valence effects on the perception of neutral faces with direct and averted gaze
(Elsevier, 2018-05-01)Most face processing research has investigated how we perceive faces presented by themselves, but we view faces everyday within a rich social context. Recent ERP research has demonstrated that context cues, including ... -
Joint Modulation of Facial Expression Processing by Contextual Congruency and Task Demands
(MDPI, 2019-05-17)Faces showing expressions of happiness or anger were presented together with sentences that described happiness-inducing or anger-inducing situations. Two main variables were manipulated: (i) congruency between contexts ... -
Neural processing of fearful and happy facial expressions during emotion-relevant and emotion-irrelevant tasks: A fixation-to-feature approach
(Elsevier, 2016-09-01)Research suggests an important role of the eyes and mouth for discriminating facial expressions of emotion. A gaze-contingent procedure was used to test the impact of fixation to facial features on the neural response to ... -
One versus two eyes makes a difference! Early face perception is modulated by featural fixation and feature context
(Elsevier, 2018-12-01)The N170 event-related potential component is an early marker of face perception that is particularly sensitive to isolated eye regions and to eye fixations within a face. Here, this eye sensitivity was tested further by ... -
Species sensitivity of early face and eye processing
(Elsevier, 2011-02-25)Humans are better at recognizing human faces than faces of other species. However, it is unclear whether this species sensitivity can be seen at early perceptual stages of face processing and whether it involves species ...
